BELL.

SPECIFICATION forming part of Letters Eatent N 0. 450,819, dated April 21, 1891.

' Application filed December 15, 1890. Serial N0.3'74,725. (No model.)

To all whom it may concern.-

Be it known that I, VALDO L. UPSON, of Meriden, in the county of New Haven and State of Connecticut, have invented new Improvements in Bells; and I do hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which to said drawings constitute part of this specification, and represent, in

Figure 1, a central section of the bell, showing the clock-work and parts in side View; and Fig. 2, a plan view, the bell removed,

parts broken away to show the escapementwheel.

This invention relates to an improvement in that class of bells in which a clock mechanism is adapted to hold the power in reserve,

which when liberated will cause the hammer of the bell to operate so long as the power is free to so operate the hammer, the time of such freedom depending solely upon the act of the operator. These bells are usually employed for door-bells, and being arranged upon one side of the door with a push-button upon the outside, a spindle upon the inside operates to disengage the power whenever the push is applied, but to cause the suspension of power whenever the push-button is free.

The object of my invention is to construct such a bell so that it may be operated either as a door-bell employing a push-button or by 5 other connections, as occasion may require,

thus adapting the bell to several different arrangements of connections for releasing the power; and the invention consists in the construction, as hereinafter described, and particularly recited in the claim.

A represents the base, which is adapted for the support of the bell.

B represents the bell, which is of the usual form, and, set over the base, forms a chamber, within which the operative mechanism is arranged. This operative mechanism consists of a clock-work arranged between a plate C and the base A,the plate C carrying a central post D, to which the bell is secured in the usual manner.

E represents the spring-arbor, which extends through the post D and is provided with a suitable key F upon its outer end, so that the spring. may be wound, the spring being held by the usual pawl and ratchet-a mechanism too well known to require detailed description.

G represents the escapement-wheel, which communicates by a train of gearing with the mainspring II of the arbor E, and so that when the said escapement-wheel is free the spring will cause it to revolve rapidly.

I represents the verge, which is arranged upon an arbor J, and so as to be operated upon by the escapement-wheel Gin the usual manher. The arbor J of the verge carries the hammer K, also in the usual manner, so that the hammer, under the oscillatory movement of the shaft J is given a vibratorymovement in a plane parallel with the plane of the bell, and so as to impart rapid blows by the hammer to the bell.

To engage the clock-work so that the power may be held in reserve, a lever is hung upon a pivot L on the base. This lever is of L shape and composed of two arms l\[ N. The one arm M extends from the pivot toward the center and outside or below the base and is provided with a spring 0, the tendency of which is to force the arm ill away from the base. The other arm N extends at substantially right angles to the base and is constructed with a nose P, which is adapted to normally stand in the path of a stud Q on the escapement-wheel, and when so standing the escapement-wheel is prevented from rotation, and consequently the power held in suspense; but upon turning the leverL, so as to take its noseP out of the path of the stud Q on the escapement-wheel, the said wheel is free to go revolve and the power therebyliberated, and so long as the power thus remains free the escapementwheel C will revolve and a corresponding vibration and operation of the hammer be continued; but when the lever is free the spring 0 will return it, so as to bring its nose P into the path of the stud Q, and thus arrest the further operation of the clock-work and hold the power in suspense.

It will be understood that the spring is to I03 be wound from time to time, as in similar clock-work.

l outer end.

the power, and when the pushris removed the spring will return the lever and the pushbutton.

To adapt the bell for other uses, as for a table-bell, the lever is constructed with a third arm U, which extends outward substan-W tially parallel with the plane of the base and between the base and the bell. This arm forms a finger'piece, upon which the finger may be applied with pressure, so as to turn the lever to disengage the power, as indicated in broken lines, or the arm U may be employed for the connection of awire, so thata pull upon the wire from a distant point will operate to disengage the power, the power be- 2 5 ing re-engaged whenever the pull ceases. By

this construction the bell isadapted to various uses, first, as a bell to apply directly to one side of a door with a push upon the opposite side, or applied at some distant point with connection made by a run of wire, or the bell may be used as a call-bell for table or other purposes, the base serving as a rest to support the bell upon the table, while the arm .U serves as a finger-piece by which to set the bell in operation,

I do not wish to be understood as claiming,

broadly, a bell having a spring clock-work combined therewith with means for engaging said clock-work so as to hold the power in suspense, and whereby upon the releasing of the power the bell will be set 'in operation, as such, I am aware, is not new; but

What I do claim is In a bell substantially such as described, the combination of the base A, the bell B, supported thereon, a spring clock-work upon said base and Within the said bell carrying an escapeinent-wheel with verge and hammer, the said clock-work being adapted through said verge and hammer to impart the required vibratory striking movement to the hammer, a three-armed lever L M U hung in the said base, the one arm L constructed with a nose adapted to normally stand in the path of a corresponding, stop in the clock-work, said arm M extending inward and substantially parallel with the base, but outside the base, the other arm U extending outward between the bell and base, and with a spring 0, the tendency of which is to yieldingly hold the said lever in its normal position, all substantially as and for the purpose described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
